Although l have herein shown and described only one form or" battery embodying` my invention, and have explained only one method embodying my invention, it is understood that various changes and modifications may bemade therein Within the scope of the appended claims without departing from the spirit and scope ot my invention.

Having thus described my invention, what l claim is: e

1. The method oit locking a retaining sleeve in. place on the terminal post of an electric battery, which consists in providing one end ot said sleeve with a comparatively thin flange, and forcing a portion of said flange into the post.

2. The method of locking aY retaining sleeve in place on the terminal post ol an electric battery, which consists in providing one end of said' sleeve with a comparatively thin llange, and forcing said flange into the post at diametrically opposite points with a snit-able compressing tool.

An electric battery comprising a cell cover provided with a hole, a terminal post projecting through said hole, a. gasket of resilient material interposed between said post, and the wall ot said hole, and a retaining sleeve carried by said post and engaging said gasket, a portion of said sleeve being forced into the post to hold thesleeve in place on the post. e

4L. An electric battery comprising a cell cover provided with a hole, a terminal post projecting through said hole, a gasket sleeved on said post and provided with an annular recess, and a retaining sleeve mounted on said post and projecting into said recess to force said gasket against the post and the wall of said hole, a portion of said sleeve beingforced into the post to hold the sleeve in place on the post.

5. An electric battery comprisinga coll cover provided with a hole, av terminal post projecting through said hole, a sleeve mounted on said post, and resilient sealing means located between said sleeve and said post and between said sleeve and the Wall ol' said hole, a, portion of said sleeve being forced into the post to hold the sleeve in place on the post.y

ln testimony whereof I allix my signature.
